Question

A balanced diet should contain $12\%$ of proteins, $25\%$ of fats, and $63\%$ of carbohydrates. If a child needs $2600$ calories in this food daily, find in calories the amount of each of these in his daily food intake.

Answer 1

In a balanced diet of $2600$ calories, $12\%$ is protein.

$\therefore$ Amount of protein in food intake $=12\%$ of $2600=\frac{12}{100}\times 2600=312$

Similarly, a balanced diet contains $25\%$ fats.

$\therefore$ Amount of fats in food intake $=25\%$ of $2600=\frac{25}{100}\times 2600=650$

Similarly, a balanced diet contains $63\%$ carbohydrates.

$\therefore$ Amount of carbohydrates in food intake $=63\%$ of $2600=\frac{63}{100}\times 2600=1638$
